<p>CSS3带给我们很多便利的东西，而颜色渐变可以代替之前用PS等一点点做图片。</p>
</blockquote>
<ul>
<li><p>CSS3 渐变（gradients）可以让你在<strong>两个或多个指定的颜色之间显示平稳的过渡。</strong></p>
</li>
<li><p>以前，你必须使用图像来实现这些效果。但是，通过使用 CSS3 渐变（gradients），你可以减少下载的时间</p>
</li>
<li><p>和宽带的使用。此外，渐变效果的元素在放大时看起来效果更好，因为<strong>渐变（gradient）是由浏览器生成的。</strong></p>
</li>
<li><p>CSS3 定义了两种类型的渐变（gradients）：</p>
<ul>
<li><strong>线性渐变（Linear Gradients）- 向下/向上/向左/向右/对角方向</strong></li>
<li><strong>径向渐变（Radial Gradients）- 由它们的中心定义</strong></li>
</ul>
</li>
<li><h2 id="CSS3-线性渐变："><a href="#CSS3-线性渐变：" class="headerlink" title="CSS3 线性渐变："></a>CSS3 线性渐变：</h2><ul>
<li><p>为了创建一个线性渐变，你必须<strong>至少定义两种颜色节点</strong>。颜色节点即你想要呈现平稳过渡的颜色。同时，你也可以设置一个起点和一个方向（或一个角度）。</p>
</li>

<li><p>如果你想要在渐变的方向上做更多的控制，你可以定义一个角度，而不用预定义方向（to bottom、to top、to right、to left、to bottom right，等等）。</p>

<li><h4 id="语法"><a href="#语法" class="headerlink" title="语法:"></a>语法:</h4><figure class="highlight css"><table><tr><td class="code"><pre><span class="line"><span class="selector-tag">background-image</span>: <span class="selector-tag">linear-gradient</span>(<span class="selector-tag">angle</span>, <span class="selector-tag">color-stop1</span>, <span class="selector-tag">color-stop2</span>);</span><br></pre></td></tr></table></figure>
</li>
<li><p>角度是指<strong>水平线和渐变线之间的角度</strong>，<strong>逆时针方向计算</strong>。换句话说，0deg 将创建一个从下到上的渐变，90deg 将创建一个从左到右的渐变。</p>

</li>
<li><p>但是，请注意很多浏览器（Chrome、Safari、firefox等）的使用了旧的标准，**即 0deg 将创建一个从左到右的渐变，90deg 将创建一个从下到上的渐变。换算公式 **<code>90 - x = y</code> 其中 x 为标准角度，y为非标准角度。</p>

<li><p>CSS3 渐变也支持透明度（transparent），可用于创建减弱变淡的效果。</p>
</li>
<li><p>为了添加透明度，我们使用 <code>rgba()</code> 函数来定义颜色节点。<code>rgba()</code> 函数中的最后一个参数可以是从 0 到 1 的值，它定义了颜色的透明度：<strong>0 表示完全透明，1 表示完全不透明。</strong></p>

<li><p>下面的实例演示了从左边开始的线性渐变。起点是完全透明，慢慢过渡到完全不透明的红色：</p>
